MPF supports segment displays and alpha numeric displays. There are several hardware options available: Segment Display Platforms in MPF.

1. Configure your segment displays in MPF config

You can use the following tested config snippet as a starting point to implement segment displays (make sure to use the correct numbers for your hardware).

your_machine_folder/config/display.yaml

#config_version=5

segment_displays:
  display1:
    number: 1
  display2:
    number: 2
  display3:
    number: 3
  display4:
    number: 4
  display5:
    number: 5

segment_display_player:
  # empty all displays on game start and setup display5
  game_start:
    display1:
      text: ""
    display2:
      text: ""
    display3:
      text: ""
    display4:
      text: ""
    display5:
      text: "{current_player.ball:d}"

  # clear only display5 after game
  game_ended{machine.player1_score > 0}:
    display1:
      text: "{machine.player1_score:d}"
  game_ended{machine.player2_score > 0}:
    display2:
      text: "{machine.player2_score:d}"
  game_ended{machine.player3_score > 0}:
    display3:
      text: "{machine.player3_score:d}"
  game_ended{machine.player4_score > 0}:
    display4:
      text: "{machine.player4_score:d}"
  game_ended:
    display5:
      text: ""

  # flash display on player turn
  player_turn_started.1{number==1}:
    display1:
      action: flash
  player_turn_ended.2{number==1}:
    display1:
      action: no_flash
  player_turn_started.3{number==2}:
    display2:
      action: flash
  player_turn_ended.4{number==2}:
    display2:
      action: no_flash
  player_turn_started.5{number==3}:
    display3:
      action: flash
  player_turn_ended.6{number==3}:
    display3:
      action: no_flash
  player_turn_started.7{number==4}:
    display4:
      action: flash
  player_turn_ended.8{number==4}:
    display4:
      action: no_flash

  # show score when adding players
  player_added.1{num==1}:
    display1:
      text: "{players[0].score:d}"
  player_added.2{num==2}:
    display2:
      text: "{players[1].score:d}"
  player_added.3{num==3}:
    display3:
      text: "{players[2].score:d}"
  player_added.4{num==4}:
    display4:
      text: "{players[3].score:d}"

2. Implement virtual segment displays

If you don’t have or want phyiscal segment displays you can also emulate them using the following slides:

slides:
  segment_displays:
    widgets:
      - type: text
        text: (player1|score)
        number_grouping: true
        min_digits: 2
        font_name: ten_segment
        color: blue
        x: 620
        y: 724
        font_size: 240
        anchor_x: right
        anchor_y: bottom
        z: 2
# show slide on game start
slide_player:
  game_started: segment_displays

This example is tested to be valid MPF and MPF-MC config. Additionally, our integration test passed. Click to show the test and full config.

    widgets:
      - type: text
        text: (player1|score)
        number_grouping: true
        min_digits: 2
        font_name: ten_segment
        color: blue
        x: 620
        y: 724
        font_size: 240
        anchor_x: right
        anchor_y: bottom
        z: 2
# show slide on game start

  game_started: segment_displays
